    摘要: An apparatus for and a method of preventing bumping and falling of an automatic travelling cleaner wherein a situation of the cleaner is determined by sensing a variation of flow rate of a fluid in an extension pipe depending on a gap between an intake port and a surface to be cleaned, thereby deriving a suction work ratio or sensing revolutions and a current value of a cleaning motor or a torque value of each travel motor, and then determining a travel, a bumping, and a step sensing, based on the sensed value. The present invention eliminates the provision of a plurality of sensors densely arranged around a cleaner and adapted to sense bumping and falling of the cleaner and thus eliminates the requirement of additional devices for the sensors. This reduces the manufacture costs.
